Anne Boleyn was a very accomplished young woman. She was educated in France and was known for her wit and intelligence. She strongly believed in the Reformation and really wanted Henry to break from Rome, not just to marry him.
Contrary to the rumors, Henry was pleased with Elisabeth's birth and hoped for a son. After a few years of marriage and two miscarriages, Henry began to turn his attention to her cousin, Jane Seymour. Henry desperately wanted a male heir and blamed his previous two wives.
Henry made up accusations of witchcraft, incest, and adultery and had Anne arrested and imprisoned in the Tower of London. She was found guilty on all charges and her own uncle read her death sentence. She had to die for Henry's lust for a male heir.
